Corsair K70 or Gigabyte Osmium

I have been interested in the K70 since it was announced and had plans to buy it at the end of this month.
Yesterday, however, I was browsing Amazon and stumbled across the Gigabyte Osmium. After reading into this board a little more, I realised that it MIGHT be a worthy competitor to the K70 and I was wondering what one you would suggest out of the 2?
I was looking at the Cherry MX Red version of the Osmium, BTW.
